Description

Technical Field

[0001] The utility model relates to a peeling knife and a fruit batch peeling device, belonging to the technical field of fruit peeling equipment. Background Art

[0002] In the fruit processing industry, especially those fruits rich in nutrition and unique flavor, such as apples, pears, persimmons, kiwis, etc., they can not only be eaten fresh, but also often processed into canned food, juice and other products to meet the different needs of consumers. However, in the deep processing of fruits, peeling and core removal is a crucial link.

[0003] At present, most factories and workshops still use manual peeling and core removal, which is very inefficient. Faced with a large number of fruits that need to be processed, manual operation is often time-consuming and labor-intensive, and long hours of work can easily lead to worker fatigue, which in turn affects the effect of peeling and core removal. In addition, due to the uncontrollability of manual operation, the accuracy and consistency of peeling and core removal are also difficult to guarantee, which will have a negative impact on subsequent product processing and quality.

[0004] Existing peeling and core removal equipment is not ideal in terms of peeling and core removal. Due to differences in the shape, size, hardness and other factors of fruits, the equipment often cannot accurately remove the peel and core. Sometimes, the equipment will remove too much flesh, resulting in a waste of raw materials; sometimes, it will leave part of the peel, affecting the taste and quality of the product. Utility Model Content

[0005] The purpose of the utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0006] The technical solution provided by the utility model is as follows: a peeling knife, comprising a blade, a knife head, a handle, a crank, a knife handle lifting cylinder and a spring, the blade being rotatably mounted on one end of the knife head, the other end of the knife head being the knife handle, the knife handle being hinged to the crank, the cylinder body of the knife handle lifting cylinder being mounted on the crank, a support rod being provided on one side of the knife handle, the driving shaft of the knife handle lifting cylinder being in contact with the support rod, the knife handle being able to swing around a hinge point with the crank under the action of the knife handle lifting cylinder, and a spring being connected between the crank and the support rod.

[0007] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: the utility model realizes the function of floating cutting on the surface of the fruit by hingedly connecting the handle to the crank and connecting a spring between the crank and the handle. This floating cutting method not only ensures that the flesh will not be accidentally cut off during the cutting process, but also can cut extremely thin peels, greatly reducing waste. In addition, the handle lifting cylinder can drive the cutter head and the blade away from the fruit in the second half of the rotation of the peeler, thereby avoiding unnecessary over-cutting. The peeler of the utility model is reasonably designed and can effectively improve the peeling effect and reduce waste.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

The cylinder body of the horizontal feeding cylinder 305 is fixed on the equipment frame 1, and the driving shaft of the horizontal feeding cylinder 305 is connected to the first bracket 304. The first bracket 304 can move along the Y-axis direction under the driving action of the horizontal feeding cylinder 305.

[0053] In this embodiment, the number of the fruit axis 2, the peeling knife 4, the loading cup 301 and the core removing knife 7 is four. Of course, the number of the fruit axis 2, the peeling knife 4, the loading cup 301 and the core removing knife 7 can be more or less. As long as the number of the fruit axis 2, the peeling knife 4, the loading cup 301 and the core removing knife 7 is adapted to meet the rhythm requirements, it should be within the protection scope of the present invention.

[0054] like Figure 6 As shown, the equipment frame 1 is provided with a mounting platform 17, a driving motor 14 and a first transmission wheel 16 are provided above the mounting platform 17, a first driving wheel 15 is provided on the driving shaft of the driving motor 14, the fruit shaft 2 is mounted on the mounting platform 17 through a first bearing seat 201, and the upper end of each fruit shaft 2 passes through the first bearing seat 201 and is connected to a first transmission wheel 16, the lower end of the fruit shaft 2 extends vertically downward, the four first driving wheels 15 and the first transmission wheel 16 are connected through a belt transmission, the driving wheel rotates under the drive of the driving motor 14 to drive the transmission wheel to rotate, and then drive the fruit shaft 2 to rotate.

[0055] The fruit peeling and pitting device further comprises a fruit unloading cylinder 602, which is mounted on the mounting platform 17, and a fruit unloading push plate 601 is mounted below the mounting platform 17. The fruit unloading push plate 601 can move up and down under the driving action of the fruit unloading cylinder 602. When the fruit unloading push plate 601 moves downward, it will effectively push the fruit inserted on the fruit axis 2 toward the pitting knife 7, so that the fruit pit and the fruit pulp are separated smoothly. After completing this action, the fruit unloading push plate 601 will move upward and reset to the initial position to prepare for the next operation.

[0056] like Figure 7 and Figure 8As shown, the paring knife 4 includes a blade 401, a cutter head 402, a handle 403, a crank 404, a handle lifting cylinder 405 and a main shaft 406. The blade 401 is rotatably mounted on one end of the cutter head 402. More specifically, one side of the cutter head 402 has a concave frame, and the blade 401 is movably mounted in the concave frame. The blade 401 is provided with 4 flat-edged paring knives and / or 4 serrated paring knives. The other end of the knife head 402 is connected to one end of the knife handle 403, and the other end of the knife handle 403 is hinged to the crank 404. The cylinder body of the knife handle lifting cylinder 405 is installed on the crank 404. A support rod 415 is provided on one side of the knife handle 403, and a support platform 416 is provided on the support rod 415. The driving shaft of the knife handle lifting cylinder 405 abuts against the support platform 416. Under the action of the knife handle lifting cylinder 405, the knife handle 403 can swing around the hinge point with the crank 404. A spring 407 is connected between the crank 404 and the support rod 415. In this embodiment, the crank 404 is L-shaped, and the main shaft 406 is connected to one side of the crank 404. When the driving shaft of the knife handle lifting cylinder 405 retracts, the spring 407 plays a role, pulling the knife head 402 and the blade 401 close to the fruit for cutting. Due to the elastic force of the spring 407, the blade 401 can perform floating cutting on the surface of the fruit, ensuring that the flesh will not be cut off, and the cut peel is very thin, avoiding waste. When the drive shaft of the handle lifting cylinder 405 extends, it will move against the straight rod, so that the handle 403 rotates around the hinge point. This action will drive the cutter head 402 and the blade 401 away from the fruit, effectively preventing excessive cutting of the fruit. It also includes a tool holder, a second bearing seat 409 and a rotary knife motor 410, the tool holder has a vertical tool holder plate 408 for mounting the peeling knife 4, the second bearing seat 409 is embedded in the tool holder plate 408, the main shaft 406 is fixedly connected to the inner ring of the second bearing seat 409, and a second transmission wheel 412 is installed at one end of the main shaft 406 passing through the second bearing seat 409, the cylinder body of the rotary knife motor 410 is installed on the tool holder, and a second driving wheel 411 is provided on the driving shaft of the rotary knife motor 410, and the second driving wheel 411 is transmission-connected to the second transmission wheel 412, and the tool holder is slidingly installed on the equipment frame 1.

[0057] like Fig. 9 and 10 As shown, the fruit peeling and core removing device also includes a tool holder cylinder 413, both ends of which are mounted on the device frame 1 via a second slider rail assembly 414, the cylinder body of the tool holder cylinder 413 is fixed on the device frame 1, and the drive shaft of the tool holder cylinder 413 is connected to the tool holder. Under the driving action of the tool holder cylinder 413, the tool holder can drive the peeling knife 4 to move along the Y-axis direction.

[0058] like Figure 11-14 As shown, the fruit peeling and core removing equipment also includes a second support plate 8, a second bracket 9, a core removing knife lifting cylinder 10 and a removal cylinder 11, the four core removing knives 7 are installed side by side on the second support plate 8, the telescopic shaft of the core removing knife lifting cylinder 10 is connected to the second support plate 8, the cylinder body of the core removing knife lifting cylinder 10 is fixed on the second bracket 9, the core removing knife lifting cylinder 10 is used to drive the second support plate 8 to move up and down, the second bracket 9 is slidably installed on the equipment frame 1, the unloading dustpan 5 is arranged above the second bracket 9, and the removal cylinder 11 can synchronously drive the second bracket 9 and the unloading dustpan 5 to move along the Y-axis direction. More specifically, both ends of the second bracket 9 are slidably mounted on the equipment frame 1 via a third slider rail assembly 13, the unloading dustpan 5 is fixedly connected to the slider of the third slider rail assembly 13 via a bracket, the cylinder body of the removal cylinder 11 is fixed on the equipment frame 1, and the driving shaft of the removal cylinder 11 is connected to the second bracket 9. When the driving shaft of the removal cylinder 11 is extended or retracted, the second bracket 9 and the slider move along the slide rail, thereby driving the unloading dustpan 5, the second bracket 9, the second support plate 8 and the core removal knife 7 to move synchronously.

[0059] The core removing knife 7 is a hollow tubular structure, and a discharge port 701 is provided on the side wall of the core removing knife 7. The fruit peeling and core removing equipment also includes a conveyor belt 12, and the conveyor belt 12 is located below the equipment frame 1, and a discharge hole is provided on the discharge dustpan 5. After the core removing knife 7 passes through the fruit, the core is successfully separated from the fruit. The separated core then enters the hollow tube and slides out smoothly along the discharge port 701. Then, the core flows out through the discharge hole on the discharge dustpan 5, and finally falls from the discharge hole onto the conveyor belt 12. Subsequently, the conveyor belt 12 transports the core to a designated location. Fig.10 As shown, splitting blades 702 may be provided on both sides of the core removal knife 7, so that the fruit can be divided into two halves while removing the core.

[0060] The working method of the fruit peeling and core removing device of the utility model is as follows:

[0061] S1. First, a nearly round fruit with a certain hardness to be peeled, such as apples, peaches, pears, etc., is placed on the loading cup 301, and the horizontal feeding cylinder 305 is started. The first bracket 304 is driven by the horizontal feeding cylinder 305 and moves along the Y-axis direction to just below the fruit axis 2. At this time, the unloading dustpan 5 and the core removing knife 7 are located at the rightmost side of the third slider rail assembly 13;

[0062] S2, then, start the vertical feeding cylinder 303, the vertical feeding cylinder 303 moves to lift the first supporting plate 302 toward the fruit axis 2, after the fruit axis 2 passes through the fruit on the feeding cup 301, the feeding cup 301 is reset under the drive of the vertical feeding cylinder 303 and the horizontal feeding cylinder 305;

[0063] S3, the knife holder cylinder 413 is started to push the knife holder forward so that the peeling knife 4 is close to the fruit;

[0064] S4, when the peeling knife 4 reaches the predetermined position, the rotary motor 410 and the drive motor 14 are started. The drive motor 14 drives the fruit axis 2 to rotate, so that the fruit fixed on the fruit axis 2 rotates rapidly. At the same time, the rotary motor 410 drives the peeling knife 4 to rotate, and peels the rotating fruit. In this way, the peeling knife 4 peels the fruit while the fruit rotates rapidly.

[0065] S5. After the peeling knife 4 rotates half a circle, the fruit skin has been cleanly peeled. In order to prevent the peeling knife 4 from over-cutting the fruit flesh, the handle lifting cylinder 405 will be activated after the peeling knife 4 rotates half a circle, and the drive shaft of the handle lifting cylinder 405 will extend to push the support rod 415 to move, thereby causing the handle 403 to rotate around the hinge point. This action will drive the cutter head 402 and the blade 401 away from the fruit, ensuring that no cutting action occurs in the second half of the rotation of the peeling knife 4. Through such a design, we can effectively avoid unnecessary over-cutting of the fruit.

[0066] At this point, the peel of the fruit has been completely peeled off. Subsequently, the rotary blade motor 410 stops working, and the peeling knife 4 stops rotating. Next, the drive shaft of the handle lifting cylinder 405 retracts, and the peeling knife 4 is reset under the action of the spring 407, and the drive motor 14 also stops working, and the fruit stops rotating. The whole peeling process ends here, and the fruit is ready to perform the core removal process in step S6.

[0067] S6, the moving-out cylinder 11 is started, driving the unloading dustpan 5 and the core-removing knife 7 to move as a whole to the bottom of the fruit axis 2, the core-removing knife lifting cylinder 10 is started, the second support plate 8 is lifted upward, and the core-removing knife 7 extends upward from the through hole 501 of the unloading dustpan 5;

[0068] S7, then, the unloading cylinder 602 starts, drives the unloading push plate 601 to move downward, and pushes the fruit inserted on the fruit axis 2 to the pitting knife 7. The pitting knife 7 accurately passes through the center of the fruit and smoothly separates the pit from the flesh. Subsequently, the unloading cylinder 602 drives the unloading push plate 601 to move upward and reset, and at the same time, the pitting knife lifting cylinder 10 drives the pitting knife 7 to fall back. Then, the removal cylinder 11 works, driving the unloading dustpan 5 and the pitting knife 7 to reset as a whole. At this time, the peeled and pitted fruits slide off the unloading dustpan 5 for collection. At the same time, the separated fruit pits enter the hollow tube and slide out smoothly along the discharge port 701. Subsequently, the fruit pits flow out through the drop hole of the unloading dustpan 5, and finally fall from the drop hole onto the conveyor belt 12, which is transported to the designated position by the conveyor belt 12. The entire process is efficient and continuous, ensuring the smooth progress of fruit processing.
